DFI ARS630 Intel Core Ultra 200S LGA 1851 ATX Industrial Motherboards with W880 or Q870 Chipset and up to Quad 2.5GbE

Industrial equipment often outlives the computer inside it. A test rig, a production cell or a laboratory analyser may depend on a particular set of PCIe and PCI cards, and replacing the motherboard should not mean replacing them. The DFI ARS630 series is a 305 x 244 mm ATX motherboard for Intel Core Ultra 200S (Arrow Lake-S) processors in the LGA 1851 socket, with seven expansion slots to carry those cards forward.

DFI lists the Core Ultra 9 285 and 285T with 24 cores, the Core Ultra 7 265 and 265T with 20, and the Core Ultra 5 245, 245T, 225 and 225T with 14 or 10 cores, at 65 W or 35 W, and the board supports processors up to 125 W TDP. Four DDR5 DIMMs run in dual channel at up to 5600 MHz and hold up to 256 GB. Integrated Intel graphics drives VGA, two DP++ and HDMI 2.0a outputs for four displays.

Two chipset builds make up the range. ARS630-W880 uses the Intel W880 chipset with ECC memory support and four 2.5GbE ports on Intel I226 controllers, for multi-camera cells and segmented machine networks. ARS630-Q870 uses the Q870 chipset with two 2.5GbE ports and non-ECC memory, for systems that need the slots more than the ports.

Both boards carry two PCIe x16 Gen5 slots, which run as x16 or x8/x8, three PCIe x4 Gen4 slots, a PCIe x4 slot wired at x1 and one PCI slot. Storage is an M.2 NVMe slot at PCIe Gen5 x4, a second at Gen4 x4 or SATA and four SATA 3.0 ports with RAID 0/1/5/10, and an M.2 A-key takes DFI’s out-of-band management module. The rear panel has four USB 3.2 Gen 2 and four USB 3.2 Gen 1 ports, and headers add two USB 3.2 Gen 1, three USB 2.0, six COM ports (two RS-232/422/485, four RS-232) and 4-in/8-out DIO.

Power comes from an ATX supply on 24-pin and 8-pin connectors. The ARS630 series operates from -5 to 65 °C with CE, FCC, UKCA, RoHS, LVD and KC compliance, a TPM 2.0, a watchdog programmable from 1 to 255 seconds and Realtek ALC888S audio with S/PDIF. DFI lists Windows 10 and Windows 11 IoT Enterprise and Linux.
